Yes, meters (and the A1c) can differ, as mentioned above. Also, you get varying readings from each hand. Fairly significant at times. Wish there was a way to know which was lowest before testing (LOL).

Meters are allowed to be 20% off on their reading. Even you A1C can be off by 10%. The purpose of the meter is to all you to see a pattern as to what happens to your BG so you can maintain a proper level. It is the ups and downs that cause the damage. The meter is your guide as to what you can and can't eat.
